Description

DETAILED DESCRIPTION OF THE INVENTION The field of art to which this invention pertains is generally in the class of devices relating to valves. More specifically, it relates to a valve base used in a fluid pressure valve device.

[Conventional technology]

Industrial plants today use a variety of machines with pneumatically actuated fluid pressure controls. The fluid pressure control device used for such a machine differs from machine to machine. One conventional fluid pressure control device uses a switching valve having an exhaust flow control valve integrally attached to a switching valve body or a lid plate for the valve. Other conventional fluid pressure control devices that require an exhaust fluid control valve use a san gage plate or interface plate mounted on a diverter valve manifold or base, and an exhaust flow control valve mounted on a san gage plate or interface plate. . The problems caused by the additional use of a Saint-Gerchi plate or an interface plate to add an exhaust flow control valve to the switching valve structure, or by the addition of an integral exhaust flow valve,
Such additions add to the overall size of the diverter valve structure, add to the cost and weight of the valve structure, and add to the complexity of such valve structure. Increasing the diverter valve structure by using an integral flow control valve or by using a Saint-Germany or interface plate often results in a mechanical emergency such as a robotic device that controls the diverter valve structure. This is a drawback because it must be installed in a small space or area. Another disadvantage of using a sine-germany or interface plate to add an exhaust flow control valve to a diverter valve structure is that such plate adds additional weight to the overall valve structure, which , One drawback when the valve must be used on a robot arm that is moved between many operating positions.

[Problems to be Solved by the Invention]

The main object of the present invention is to increase the cost, increase the weight, and increase the size of the valve structure in a pneumatic control device when it is necessary to provide a flow control function by using a Saint-Gerci plate or an interface plate. To provide a new valve base that overcomes

Another object of the present invention is light weight and small structure,
It is to provide a novel valve base configured to selectively provide exhaust flow control functionality.

Another object of the present invention is to provide a novel valve base for a diverter valve structure that does not require a sun deer plate or an interface plate to provide the exhaust flow control function.

Yet another object of the present invention is to provide a novel valve base for a diverter valve structure that can be used to provide a low profile valve structure while still providing an exhaust flow control function.

[Means for Solving the Problems]

The foregoing is by providing a 5-port individual valve base having an integral flow control device, simple in construction, compact in size, economical to manufacture, and configured for use in a hydraulic valve device. To be achieved. The valve base of the present invention has a substantially rectangular outline with a top surface, a bottom surface, a front side surface, a rear side surface and an end surface. The valve base has one inlet pressure port and two exhaust ports formed on one side of the valve base. A pair of cylinder ports is formed on the other side of the valve base. All ports are connected by passages to separate vertical passages leading to the top surface of the valve base so as to communicate with corresponding passages in a hydraulic valve mounted in the valve base. The passage connecting the exhaust port to the exhaust port on the upper surface of the valve base is arranged toward the both ends of the valve base rather than outside the cylinder passage. The valve base extends inwardly from either its end face or its side face and accommodates a pair of flow control valves to actuate and enter an exhaust port on the top surface of the valve base and into the valve base. A pair of flow control valve chambers may optionally be provided to control the flow of exhaust fluid through the exhaust passageway through the exhaust ports and out.

As illustrated in FIG. 1, the valve base inlet pressure passage 22 in the upper surface 16 of the valve base 10 communicates with the inlet pressure chamber 43 through the inlet pressure passage 42 in the switching valve 11. The valve base exhaust passages 26 and 30 pass through the exhaust passages 44 and 46, respectively, and a pair of exhaust chambers 45 and
It communicates with 47. Cylinder passages 36 and 39 in the upper surface 16 of the valve base 10 communicate with cylinder chambers 49 and 51 in the switching valve 11, respectively, through cylinder passages 48 and 50, respectively.

As shown in FIG. 2, a flow control valve chamber 54 is formed in the valve base 10 and extends through the base extension 55 to allow the valve base 10 to pass through.
Extending out of. The flow control valve chamber 54 has a vertical exhaust passage.
It is aligned with the horizontal vertical exhaust hole 29 that communicates with 30. A non-elevating flow control valve, indicated generally by the numeral 56, is operably mounted in the flow control valve chamber 54.
The flow of exhaust fluid from exhaust hole 29 into passage 28 and out through exhaust port 27 is controlled by a flow control valve 56.
The flow control valve 56 has a cylindrically shaped valve body along its central front end, indicated by numeral 57. A conical valve 58 is integrally formed at the inner end of a valve body 57, which is a cylindrical portion of the flow control valve, and which is a horizontal vertical exhaust valve.
Is configured to regulate the flow of exhaust fluid past a valve seat 59 formed at the junction of the exhaust passage 28 and the exhaust passage 28. As shown in FIG. 2, the valve 58 is in a closed position relative to the valve seat 59, but when it is moved rearward, ie to the right shown in FIG. Can pass past the valve seat 59 into the passage 28 and out through the exhaust port 27.

The non-raising flow control valve 56 includes a cylindrical adjustment head 62,
It remains vertically fixed when rotated to adjust the position of valve 58. The cylindrical adjustment head 62
It has a lateral slot 63 formed in its outer end surface for rotating the adjusting head 62 by means of a suitable tool. The cylindrical adjustment head 62 is rotatably mounted in a hole 64 in the base extension 55, which has a reduced diameter shaft 65 integrally formed at its inner end. The inner end of the shaft 65 is integrally attached to the outer end of a pair of longitudinally spaced annular flanges 66 located in the hole 67, the hole 67 being at the outer end thereof.
It has a diameter slightly smaller than the hole 64 and communicates with the hole 64. A suitable o-ring seal 68 is mounted in the groove between the pair of annular flanges 66, which engages the surface of the hole 67 to provide a seal. An elongated threaded shaft 69 is integrally mounted inside the innermost one of the pair of flanges 66. A threaded shaft 69 is formed at the rear end of the valve body 57 and is operably mounted in a threaded hole 70 extending longitudinally inwardly from the rear end of the valve body 57.

As shown in FIG. 4, the outer end of the valve chamber 54 comprises a hexagonal section. The rear end portion of the flow control valve body 57 is also provided with a hexagonal periphery so as to be slidably attached to the hexagonal portion of the valve chamber 54. It will be appreciated that when rotating the flow control adjustment head 62 in either direction, the adjustment head 62 does not change its vertical position while turning the threaded shaft 62. By turning the threaded shaft 69 in the threaded hole 70, the valve body 57 moves back and forth in a linear motion without any rotation due to the sliding effect of the hexagonal rear end of the valve body 57.
